Which regulation requires organizations to report data breaches to the Information Commissioner's Office?

The regulation that requires organizations to report data breaches to the Information Commissioner's Office is the UK General Data Protection Regulation (UKGDPR). This regulation was introduced to govern data protection and privacy in the United Kingdom, establishing specific obligations for organizations regarding the handling of personal data.

Under the UKGDPR, organizations must notify the Information Commissioner's Office about personal data breaches without undue delay and, when feasible, within 72 hours of becoming aware of the breach. This prompt reporting is crucial for mitigating any potential harm to individuals whose data may have been compromised and helps to ensure that proper measures are taken to manage and investigate the breach effectively.

While other regulations, such as the Data Protection Act 1998 and various e-commerce regulations, touch upon aspects of data protection and privacy, they do not impose the same mandatory reporting requirements for data breaches to the Information Commissioner's Office as specified in the UKGDPR. The Insurance Act 2015 relates to insurance contracts and does not pertain to data privacy regulations. Thus, UKGDPR is the correct answer in relation to the duty to report data breaches.
